…ndencies (testing-library#1305)

BREAKING CHANGE: `@testing-library/dom` was moved to a peer dependency and needs to be explicitly installed. This reduces the chance of having conflicting versions of `@testing-library/dom` installed that frequently caused bugs when used with `@testing-library/user-event`. We will also be able to allow new versions of `@testing-library/dom` being used without a SemVer major release of `@testing-library/react` by just widening the peer dependency.
`@types/react-dom` needs to be installed if you're typechecking files using `@testing-library/react`.
